SUCTION-HOSE COUPLING.

To all whom it may concern.

Be it known that I, Gnoncn M. Knssnnn, a citizen of the United States,residing at Gregson, in the county of Silverbow and State of Montana,have invented certain. new and useful Improvements in Suction- HoseCouplers; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to the class of wa ter distribution, and moreespecially to de tachable hose pipe couplings, and the object of thesame is to produce a fluid-operated machine for quickly coupling anduncoupling the suction hose of the feeding pump in a mine with thebarrel of the suction pump or the pipe leading to it.

It is a well known fact among miners that every time a blast occurs inthe bottom of a shaft where a sinking pump is employed, it is necessaryto disconnect the suction hose and place it out of the way of the blastso that it will not be injured, and after the blast has been fired thehose is again let down into the mine and must be reconnected with thebarrel of the suction pump or with the pipe which leads to said pump. Bythe present method this takes much time as there are two flanges on thepipe which leads from the pump and one on the nipple connected with thehose, and there are four nuts unscrew and take care of as well as thegaskets, and both nuts and bolts as well as the gaskets are liable tofall into the shaft which necessitates getting new ones and the wholeoperation becomes slow and tedious.

It is the purpose of the present invention to shorten the time of makingthis connec' tion and breaking it, to avoid the possible loss of boltsand nuts and gaskets, to make a firmer connection between the hose andpump barrel or pump pipe than hitherto, and for this purpose to use thefluid pressure which is always present where a sinking pump is beingoperated, sometimes air, often steam, and occasionally water. Thisobject is carried out by the invention whose construction is hereinaftermore fully described and claimed, and is shown in the drawings whereinFigure l is a front elevation. Fig. 2 is a vertical section on line 22of Fig. 3. Fig. 3 is an edge view. Fig. 4 is a vertical sec-Specification of Letters Patent.

tion on line 1-4 of Fig. 1 showing the hose detached from the coupler.Fig. 5 is a horizontal section on line 5-5 of Fig. 1. Fig. 6 is aperspective detail of one of the emergency screws.

In the drawings the numeral 1 designates a frame, herein consisting oftwo horizontal plates through whose center extends an up right sleeve 2and through which at opposite sides of said sleeve extend uprightcylinders 8 in which move pistons 1 mounted on piston rods 5 whose lowerextremities are connected by a yoke 6 having a notch '2' in its frontedge. A guide rod 8 may rise from the yoke and pass through an eye 9 inone or both of the plates forming the frame, and this red and the pistonrods may be connected with the yoke by nuts 10 above and below it sothat the yoke stands ever parallel with said plates. The piston rodsmove through glands in the heads of the cylinders and may have pistonrings as usual, but these parts are not numbered as they form no portionof the present invention.

In the lower end of each cylinder is a pet cook 12, and through itsupper end opens a pipe 13 connected by a coupling 14 with any suitableexhaust 15. An inlet pipe 16 leads from the source of fluid pressure(air, water, or steam) through a valve 17, beneath which is a T-coupling18 where this inlet branches and leads thence outward and downward as at19 and into the sides of the cylinders near their lower ends. It isobvious that when this valve 17 is open and the pet cocks are closed,the inrush of fluid pressure beneath the pistons will cause them torise, and with them move the yoke; on the other hand, when the valve 17is closed and the pet cocks are open, the pistons and yoke will descendunder the weight of the hose or may be forced downward by admittingpressure at 15.

The suction hose H is connected by a coupling 20 with the lower end of apipe 22 around which is secured a cup 23 which has around it a flatflange 24 adapted to rest upon the yoke. The pipe 22 is of a size toenter the notch 7, and its upper portion is preferably ground externallyso as to make a close fit inside the sleeve 2, and the cup 23 maycontain a gasket 25 for fitting against the lower end of said sleevewhen it is drawn up against it. The yoke is pro vided with a pluralityof holes 26, and the flange 24: may have one such, numbered 260 in Fig.1, any of which are adapted to be detachably engaged by the threadedlower ends of emergency screws 27 which extend loosely upward throughholes 28 in the lower plate 1 and have eyes 29 at their upper endsadapted to engage hooks 30 depending from the upper plate 1, and theheads 32 of these screws are adapted to rest upon the lower plate whentheir threaded ends engage the holes in the yoke as dotted in Fig. 3.These heads are preferably made angular so that a wrench may be appliedthereto to draw all parts into firm connection, to raise the yoke andwith it the cup, and to cause the cup and its pipe 22 to make a closeand watertight connection at the lower end of the sleeve 2. The letter Pdesignates a pipe connected by a coupling with the upper end of saidsleeve and leading to a pump, or the pump barrel may be connecteddirectly with said upper end if preferred.

The operation of this device is as follows: When the parts stand as seenin Fig. 2, the operation of the pump creates suction through the hose Hand the water is constantly drawn out of the mine in the usual way. Whennow it becomes desirable to create a blast within the mine and it isnecessary to withdraw the hose so that it will not be injured, thepet-cocks are opened and the yoke and hose should descend by gravity tothe position shown in Fig. 1; but if not, fluid pressure is admittedthrough the pipes 13 to force the pistons downward, and the yoke movesby this pressure to the posit-ion therein shown. The cup 23 and its pipe22 are then drawn forward out of the notch 7 in the yoke, and with thecup comes the hose H which may be lifted out of the mine. All this canbe done very quickly, as there is no coupling or union to disconnect.After the explosion has occurred the hose is reinserted in the mine, thecup replaced within the notch so that its flange rests upon the yoke,the pet-cocks closed and the valve 17 opened, and the fluid-pressurecauses the rise of the pistons and with them the yoke, which latterdraws upward on the cup until it makes a close connection with the lowerend of the sleeve, and the hose is therefore coupled to the latter. Itsupper end being con nected with the pump, pumping may then be resumed.If preferred the valve 17 may be left open so that fluid-pressure willhold the parts in this position, but if it is desired to hold themrigidly connected the screws are engaged with the yoke by simplydisconnecting their eyes or rings from the hooks in the upper plate andletting them down and screwing them into the holes with which the yokeis provided for that purpose; and to make a very tight joint a wrenchmay be applied to the head of each screw and it can be turned until thegasket within the cup is compressed against the lower end of the sleeve.

Unions 18 are preferably employed in the short pipes connecting the'T-couplings 18 with the elbows of the feed pipes 19 whereby theTcouplings and the parts connected thereto may be readily detached fromsaid feed pipes.

All parts are by preference of metal, and the proportion is about asshown although that is not necessary.

Changes in unimportant details may be made without departing from theprinciple of my invention.

The combination with an upright sleeve adapted to be connected at itsupper end with a pump, cylinders at opposite sides of said sleeve,pistons therein, piston rods depending from these pistons through thelower heads of the cylinders, and connec tions for moving the pistons ineither direc tion by fluid-pressure; of a yoke connecting the pistonrods and having a notch in its front edge, a pipe removably engagingsaid notch and connected at its lower end with a hose, and a cupsurrounding the pipe and adapted to make a tight oint with the lower endof the sleeve when it is elevated by the rise of said yoke.
